rrmmicn rnonr FLAREWAY.

Be it known thatI, JOHN REID, a subject of the King of Great Britain, and residing V r at 30 Church street, in the city of New York,

in the State of New York, in the United States of America, have invented a new and useful Furnace-Front Flareway, of which the following is the specification.

The invention relates to improvements in furnace front ash pit flareway, as described in the present specification and illustrated in the accompanying drawings that form part of the same.

The invention consists essentially of the novel formation rigid with the inner wall of the furnace front, whereby an unobstructed way in the form of a ramp is furnished for the withdrawal of the ashes across the division between the front and the pit and up to the level of the ash pit flare. I

The objects of the invention are to insure a good joint between the ash pit. flare and th pit, so that the work of the fireman in removing the ashes shall be greatly facilitated; to further my work in the standardization of furnace fronts,'particularly for marine installations', though in many cases suitable for stationary plants, and in this connection to make it unnecessary to slope the flare for the different constructions of furnace, but instead merely alter the shape or size of the lip forming the way; and generally to provide in a furnace front a substantial addi tion, that will not make any material difference in the cost for itself and at the same time reduce the expense and remove the trouble and inconveniences incident to the fitting of ash pit flares to the pit mouth.

In the drawings, Figure 1 is a perspective view of the lower portion of a furnace front showing the ramp leading to the flare.

part with said back plate or any part rigid therewith and'slopes from the flare 3 joining the front plate 4: and back plate 2 at the ash openings 5 and 6. k

' It will thus be seen that the back plate casting has aramp cast ontoit. This ramp is proportioned to meet the requirements,

that is to say, the distance from the level of the ashpit flare to the bed of the pit. In

. consequence of this construction the casting Patented Feb. 24, 1920. Application m da 'ril 19, 1919. Serial N0. 291,361. W V

ations and contributes largely in standardizing many parts of the front, so that they may be stocked up and furnished to the customer immediately or as spare parts for an equipment already installed.

In Fig. 3 the ramp 8 is shown as filling in and bridging the space between the back plate 9, and the furnace mouth plate 10 and is therefore to all intents and purposes in this form a thickening ofthe flange 11 for the width of the ash pit opening, the upper side 12 of this flange sloping to the opening on a level with the edge thereof and the upper surface of the flare 13. In this construction the furnace mouth plate 10 is turned outwardly.

In the use of the front formed with this invention, the ashes are drawn out of the pit by a fire iron of any suitable type and in drawing the ashes along, the scraper iron pulls them over the ramp onto the flare and so on out of the opening through the front plate.

The necessity of having the flare slope downwardly to meet the furnace mouth is thus eliminated and further the difficulty in cident to making a good freeway for the ashes is entirely done away with and a good path provided, which will of course facilitate the work of the fireman.

The exact forms of the invention herein described and illustrated will not necessarily be closely adhered to, so various changes may be made without departing from the spirit of the invention and the protection herein granted shall not be invalidated if such changes remain within the scope of the claims for novelty following.

What I claim is 1. In a furnace front, a front plate and a back plate having an ash opening communi-V eating with the ash pit of the furnace, mg j I a ramp rigid with the said back having an'upper surface sloping ownward' late and and inwardly from the ash opening to substantially the floor of the ash pit.

bottom of the ash opening and extending downwardly and inwardly to substantially the floor of the ash pit of the furnace.

3. In a furnace front, a front plate and a back plate both having ash openings, a flare bridging the space between said openings, and a ramp extending downwardly and inwardly from the back plate to substantially flush at its higher end with said flare, said ramp being cast integral with the back plate and forming therewith a recess located at the'under side of the ramp between the same and the back plate;
